Here are the SF kibits results for the first 62 positions you posted (I did not look at the others yet).Some of them I did not find in the games, so I suspect that they were resulting positions after your chosen key moves?

Here Houdini played Bd3. That looked strange.Bishop belongs to the square g2 as the king defender and for induce pressure to the diagonal h1-a8.Houdini later admit that and played back Bf1. But what to do?

Houdini played h6.Practically speaking freely weakening king pawns-defenders setup f7-g6-h7 against opponent pawns d5-e4-f4-g2-h3 is a suicide.Sooner or later you receive f5.Do not allow to opponent prepares for killing f5.
